Tr1AL Posted March 7 Report Share Posted March 7 (edited) There is a modification to the fuel tank petcock that was recommended at the time to stop the carb giving a a lean condition this is done by removing the petrol tap from the tank taking off all its gaskets and then pull off the filter gauze underneath it sits a plastic tube, this tube needs 6mm cut off it and then make sure the cut end is open for flow of fuel then replace the gauze filter and put everything back together before fitting back on the tank , alternatively just always use the bike with the fuel tap set to the reserve position. All this information is available at SHERCO USA.COM Edited March 7 by Tr1AL Quote Link to comment Share on other sites More sharing options...

If you need SHERCO Info/parts go to splatshop.co.uk and ask to speak to Chris Pearson he has a lot of knowledge about their bikes. Best wishes Alan.
